Description
（イ）ＴＧ－ＤＴＡ測定（実施例の耐熱性向上の確認）
上記（４）で得た実施例のＰ５ＡＯＨ－ＰＥＧ、上記（ｉ）で得た比較例のＣＤポリロタキサン、さらに参考として上記（１）で用いたＰＥＧ２００００、上記（２）で中間生成したＰ５ＡＯＨ、上記（３）で中間生成したＰｓｅｕｄｏＰ５ＡＯＨ－ＰＥＧについて、ＴＧ－ＤＴＡ測定を行った。
詳しくは、示差熱・熱重量（ＴＧ－ＤＴＡ）同時測定装置（日立ハイテクノロジーズ製 ＳＴＡ７２００）を用い、サンプルパンとして白金を用いて、Ｎ２ガス気流（１０ｍＬ／分）中で、熱分解昇温速度：１００～３００℃…１℃／分、３００～９００℃…１０℃／分の条件下、測定した。加熱前重量を基準（１００％）にして加熱前重量に対して５０％重量減少した温度を熱分解温度（５０％重量減）として表２に示す。
さらに、実施例のＰ５ＡＯＨ－ＰＥＧと比較例のＣＤポリロタキサンについては、乾燥空気気流（１０ｍＬ／分）中でも、同様の条件下、測定した。加熱前重量を基準（１００％）にして加熱前重量に対して５％重量減少した温度を５％重量減少温度、同様に１０％重量減少した温度を１０％重量減少温度として表２に示す。
(B) TG-DTA measurement (confirmation of heat resistance improvement in Examples)
The P5AOH-PEG of the example obtained in (4) above, the CD polyrotaxane of the comparative example obtained in (i) above, the PEG20000 used in (1) above, the P5AOH intermediately produced in (2) above, and the above The PseudoP5AOH-PEG intermediately produced in (3) was subjected to TG-DTA measurement.
Specifically, using a differential thermal/thermogravimetric (TG-DTA) simultaneous measurement device (Hitachi High-Technologies STA7200), using platinum as a sample pan, in a N gas stream (10 mL / min), pyrolysis temperature rise Speed: 100 to 300°C...1°C/min, 300 to 900°C...10°C/min. Based on the weight before heating (100%), the temperature at which the weight is reduced by 50% relative to the weight before heating is shown in Table 2 as the thermal decomposition temperature (50% weight reduction).
Furthermore, P5AOH-PEG of Example and CD-polyrotaxane of Comparative Example were measured under similar conditions in a dry air stream (10 mL/min). Based on the weight before heating (100%), the temperature at which the weight is reduced by 5% is shown in Table 2 as the 5% weight reduction temperature, and the temperature at which the weight is reduced by 10% is also shown in Table 2 .
